Applicant's summary and conclusion

Conclusions:
Equilibrium partition occurs primarily to soil and some to sediment.
Executive summary:

Mackay fugacity modelling (level 1) indicates that, in the absence of degradation, the substance partitions mainly to soil (>98.5%) with the remainder to the sediment phase. None would be present in water or the air.
